Tyger Tyger Burning Bright

Recently I've stumbled across someone who could work very well as a reference for another one of my OCs and also pictures of someone with their hair dyed in rainbow colours and I'm feeling like the alignment of these two things is telling me I need to attempt drawings of some of my OCs soon (though I'd also be tempted to give that particular character hair dyed blue and yellow sometimes. For... reasons) 

I am kind of stuck on the idea of Mary Watson dying but she was actually turned by a vampire so a while after she dies she comes back as a vampire but Watson is still kind of like... nope, she is still dead to me. Moriarty and Moran maybe take her under their wing then.
